I tried to compile the sources for Cortex-M4.
It's my first attempts and I really confused... I started with `make menuconfig' where I disabled MMU-options and chose STMicro STM32 processor. Then I lunched 'make' and got these errors.

Thanks a lot for your help.

Aleksey,

  • Emcraft kernel tree on GitHub doesn't include configuration files for
    STM32. Only customers of our products receive sample projects with the
    kernel configuration files for the given BSP.
    However it's not so hard to figure out what options need to be enabled.
    Git history provides sufficient information on that.
  • We recommend to use CodeSourcery arm-2010q1 for building. The
    download link is available on the Emcraft Site.

Regards,

Sergei Poselenov,
Emcraft Systems

char: random: Workaround the Illegal unaligned access

In extract_buf(), hash will be copied to out.
Compiler optimizes memcpy() aggresively and does not test the unaligned
destination address. Specify aligned attributes to workaound it.
